【摘要】：試驗選用480只210日齡羅曼褐蛋雞,隨機分為5組,每組4個重復,每個重復24只雞,對照組飼喂基礎飼糧,4個試驗組分別在基礎飼糧中添加3%、6%、9%和12%的桑葉粉,試驗期56d。結果表明:與對照組相比,4個試驗組的血清丙二醛、谷胱甘肽過氧化物酶、補體C3和補體C4含量均無顯著差異著(P005);試驗組Ⅱ極顯著地提高了血清總抗氧化能力含量(P001);試驗組Ⅳ血清超氧化物歧化酶、免疫球蛋白G、腫瘤壞死因子顯著提高(P005);試驗組血清免疫球蛋白A、白細胞介素-1顯著或極顯著提高(P005);除試驗組Ⅰ,其余各組血清免疫球蛋白M含量極顯著提高(P001);試驗組Ⅱ和試驗組Ⅲ血清的白細胞介素-6含量均有極顯著增高(P001),試驗組Ⅳ的白細胞介素-6含量有提高,但差異不顯著(P005)。血清超氧化物歧化酶、3種免疫球蛋白和2種白細胞介素含量均呈現隨添加量增加而增高的趨勢。綜上所述,桑葉粉在蛋雞養(yǎng)殖中具有增強免疫力、提高抗氧化能力等作用,建議桑葉粉合理添加量為3%~6%。
[Abstract]:480 210-day-old Roman brown laying hens were randomly divided into 5 groups, with 4 replicates in each group and 24 chickens in each replica. The control group was fed with basic diet. 9% and 12% mulberry leaf powder were tested for 56 days. The results showed that there was no significant difference in serum malondialdehyde, glutathione peroxidase, complement C3 and complement C4 between the four groups (P005). The content of serum total antioxidant capacity (P001) and serum superoxide dismutase (SOD), immunoglobulin G (IGG) and tumor necrosis factor (TNF- 偽) were significantly increased in group 鈪，
